Description
Take a statement doing long GIS computation (it takes minutes):
SELECT
|
st_buffer(st_buffer(ST_GEOMFROMTEXT('POLYGON((10 10, 10 20, 20 20, 20 10, 10 10))'),1), |
(st_length(multilinestringfromtext(' MULTILINESTRING( ( 2 2, 2 8, 8 8, 8 2, 2 2 ), ( 4 4, 4 6, 6 6, 6 4, 4 4 ) ) ')) )); |
and try to run SHOW EXPLAIN (or SHOW ANALYZE) on it. The result will be:
MariaDB [test]> show analyze format=json for 398;
|
ERROR 1205 (HY000): Lock wait timeout exceeded; try restarting transaction
|
Note that KILL or KILL QUERY are able to kill the statement.
